Which sequence has 3n as its nth term

3n,   let n = 0, 1, 2, 3, 4, 5,

When n= 0,  3n = 3*0 = 0

When n= 1,  3n = 3*1= 3

When n= 2,  3n = 3*2 = 6

When n= 3,  3n = 3*3 = 9

When n= 4,  3n = 3*4 = 12

When n= 5,  3n = 3*5 = 15
...
Sequence   3n    =  0, 3, 6, 9, 12, 15,            for n = 0, 1, 2, 3, 4, 5,

1.3 and 1 1/3 are both closest to 1. hope this ; )
